But these aren’t the only plants that are dominating. According to Chelsea Flower Show fans, foxgloves and lupins have been the stand-out species this week.

Food writer Nigel Slater wrote on Instagram, 'If there is one flower dominating #rhschelsea this year it is the foxglove and I couldn’t be happier.'

As for growing the award-winning flowers in your own garden? Horticulture Week reports that the first and third place entries in the Plant of the Year shortlist are already going into garden centres.
